In his op-ed that (properly) condemns Uganda-based Joseph Kony for leading a group that kills wantonly, he writes:

This is ultimately the work and trademark of a single man: Joseph Kony, the most carnivorous killer since Idi Amin. As the military and spiritual leader of the Lord's Resistance Army (LRA), Kony is a combination of serial murderer and cult leader.

Gerson goes on to say that the U.S. State department, as well as various African states, should condemn and try to stop Kony and the LRA.

What Gerson's doesn't tell you is that the LRA:

... claims to be based on the Christian Bible and the Ten Commandments.

It is led by Joseph Kony, who proclaims himself the "spokesperson" of God and a spirit medium, primarily of the Christian Holy Spirit ...

Where's Gerson call for Christian groups to get involved and (at the very least) challenge the theology behind the group? Or is it now, according to Gerson, only secular states that should bother with these matters?
